Pixel circuit, method for driving the pixel circuit and display device

A pixel circuit comprising:

• a plurality of rows of gate lines;
• a plurality of rows of read-control lines;
• a plurality of pixel unit circuits arranged in rows and columns;
• and
• a driving module;
• wherein each of the plurality of pixel unit circuits includes a pixel unit and a pixel compensation unit, and each pixel compensation unit is coupled with a corresponding row of read-control line;
• the driving module includes a gate drive circuit coupled with the rows of gate lines, and a signal generation unit;
• the signal generation unit is coupled with the gate drive circuit and the pixel compensation units, and is configured to generate a read-control signal and a gate drive-control signal, transmit the read-control signal to a corresponding row of read-control line and transmit the gate drive-control signal to the gate drive circuit;
• the gate drive circuit is configured to, based on the gate drive-control signal, generate a plurality of gate drive signals to control the rows of gate lines to be turned off in a reading period;
• wherein, for one of the plurality of pixel unit circuits, the pixel compensation unit includes a light sensing module configured to convert a light signal emitted by the pixel unit into a corresponding electrical signal;
• and the signal generation unit is configured to generate the read-control signal based on the electrical signal.
